I used to get him recommended in my social media feeds all the time, but as I'm trying to use those less, I kinda forgot about him.
His schtick here is that he hits up random people on Omegle and asks them to give him a few random words. He then comes up with a freestyle on the spot using those words. I'm not too familiar with the freestyle scene, but to me, he really looks out of this world.
